We ported a project of ours to use HDRP in 2018.2.2. as a test. First thing we noticed is that all custom shaders go pink. After some googling I read in some post around june 2018 that custom shaders (and even the Graph) are not supported (yet?). Some people said rewrite them, but i don't find any hint as to what to rewrite or how, also read "make a custom pipeline", but since there is not to much documentation yet it's kind of a blank on how to do that either. Is there any work around at the moment to get them to work?
